**Problem Description:**Suppose you want to test the claim that the paired sample data given below come from a population for which the mean difference is \( \mu_d = 0 \).| | x | y ||--------|----|----|| Data | 86 | 84 || | 57 | 81 || | 59 | 63 || | 62 | 60 || | 88 | 94 || | 86 | 62 || | 90 | 74 |**Instructions:**Use a 0.05 significance level to find the following:(a) The mean value of the differences \( \bar{d} \) for the paired sample data.\[ \bar{d} = \text{[Input Answer]} \](b) The standard deviation of the differences \( s_d \) for the paired sample data.\[ s_d = \text{[Input Answer]} \](c) The t test statistic.\[ t = \text{[Input Answer]} \](d) The positive critical value.\[ t = \text{[Input Answer]} \](e) The negative critical value.\[ t = \text{[Input Answer]} \](f) Does the test statistic fall in the critical region?- A. Yes- B. No(g) Construct a 95% confidence interval for the population mean of all differences \( x - y \).\[ \text{Lower Limit} < \mu_d < \text{Upper Limit} \]

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. ASsume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms.
